A modem or LAN connection is convenient for changing the encoder s configuration remotely or if PORT A is permanently wired as a data input The configuration program SETTE32 is available from Ross Video Installing SETTE32 To install SETTE32 on the transmit computer s hard drive 1 Fetch the latest setup software from the Ross Video website to the computer to be used to configure the TES Click the start button on the task bar and select the Run option In the Open box type click on the Browse button and find the SETUP EXE saved from the website Click on OK Follow the Install Shield instructions There are three methods involved in configuring the encoder e Connect a null modem cable between the transmit computer and PORT A Note The first time you configure the encoder you should use PORT A On subsequent connections you have the choice of three types of connection or e Connect the transmit computer s and the encoder s modems to phone lines or e Connect the transmit computer s LAN card and the encoder s LAN card to a LAN gt Put the encoder in setup mode this is not necessary for the LAN connection if the encoder s IP address has already been set up gt Run SETTE32 e The last two steps are explained in more detail in the following sections Putting the Encoder in Setup Mode The encoder is designed to power up and run with the parameters stored in configuration memory To initiall

Continuity Index and Packet Structure of each 30 byte block must be Hamming perfect If the encoder does not receive Hamming perfect bytes when it is expecting them it discards data until it finds two Hamming perfect bytes Once all 30 bytes are received the encoder inserts the 3 byte packet address and the 30 received bytes into one of the TV lines enabled for insertion This mode is used with applications such as VBinet where total control of NABTS formatting is required 33 Byte Transparent This mode is similar to 30 byte transparent mode except that the 3 byte packet address is also included in the data received from the transmit computer This has the advantage of offering you complete control over the packet address allowing data with different packet addresses to be inserted from one stream As a result when this mode is selected the entry displayed in the Packet Address field is changed to and cannot be altered In this mode the first 5 bytes of each 33 byte packet 3 byte packet address 1 byte continuity index and byte packet structure byte must be Hamming perfect in order to allow the encoder to synchronize to the incoming data stream 8 Bit Packet and Bundle FEC The two 8 bit FEC modes have many functional similarities Both are discussed in this section These data modes using the advanced Ross Video FEC permit 8 bit data to be sent to Ross Video decoders The decoders can then perform error correction on the received
